The company said it expands its ‘pioneering’ use of metal-hydrogen energy storage technology as an advantageous solution compared with lithium-ion and other alternatives. EnerVenue will begin shipping ESVs to customers in 2023.

Based on decades of use with NASA and other aerospace applications, EnerVenue has significantly cost-reduced materials to bring battery durability, safety, and flexibility benefits to grid-scale, commercial and industrial deployments.

The new ESV solution provides enhanced flexibility in how customers can stack and install the vessels to build and scale their energy storage capacity.

Customers can cycle ESVs up to three times per day without rest, and the batteries have an expected lifetime of 30 years or 30,000 cycles.

ESVs continue to deliver 86% capacity beyond 30,000 cycles, providing a second asset life that the company claims lithium-ion batteries cannot match. The solution’s metal-hydrogen technology further differentiates from li-ion by offering improved fire safety.

ESVs have been tested and demonstrate no thermal runaway or propagation risk, and there is no need for costly, preventative fire suppression systems, and they are ‘highly configurable’ and scalable.

They also reduce OPEX and CAPEX costs compared with li-ion, eliminating any need for expensive augmentations, excessive oversizing, or extensive maintenance during a project’s lifetime. With recyclable components, ESVs are also more sustainable and environmentally responsible than li-ion.

ESVs are built to thrive even in extreme temperatures and other environments where grid-scale li-ion batteries struggle. The product also features flexible charge/discharge rates and can discharge to 100% (deep discharges permanently damage li-ion batteries), giving system owners the latitude to capitalise on a broader range of revenue stream opportunities.

Majid Keshavarz, Chief Technology Officer, EnerVenue, said its new ESVs deliver a meaningful upgrade to the customisation and ease with which customers and partners can plan, and expand, utilising its proven battery technology.

EnerVenue backs its ESVs with the Capacity Assurance extended warranty. Launched in October, customers selecting Capacity Assurance are guaranteed 88% capacity for up to 20 years or 20,000 cycles.
